Wallabies back James O'Connor has been ruled out of this afternoon's Rugby World Cup pool match against Uruguay, pulling out with injury.
O'Connor was originally set for limited minutes off the bench but the utility back got injured in training this morning.
The Wallabies have opted to take the cautious route with O'Connor, bringing Samu Kerevi into the matchday 23.
Backrowers Jack Dempsey and Lukhan Salakaia-Loto will also be donning different jerseys in the match after an embroidery mishap.
Rugby.com.au reports Dempsey will wear the no. 6 jersey while Salakaia-Loto will don the no.8, though both will be playing in their originally named positions.
Australia needs to lose to Uruguay without a bonus point for Fiji to still have a chance of reaching the quarterfinals of the 2019 Rugby World Cup.
Fiji will then need to claim a bonus-point win over Wales next Wednesday.
If the Wallabies lose to Uruguay without a bonus point today they do not get any points and remain in third place with 6 points in Pool D.
Fiji is currently second in Pool D with 7 points.
Based on this, the Flying Fijians will have a high chance of finishing second in Pool D with 12 points if they beat Wales with a bonus point next Wednesday.
In this scenario, Fiji will still finish second in Pool D even if Australia beats Georgia with a bonus point because the Wallabies will only finish with 11 points while Fiji will finish with 12 points.
Australia will face Uruguay at 5.15pm while England will face Argentina at 8 o'clock tonight.
Samoa will also clash with Japan at 10.30 tonight.
The All Blacks face Namibia at 4.45pm tomorrow while France and Tonga clash at 7.45pm tomorrow.
